Typedef Documentation

ElfSymbolVersionsEntries

using gtirb::provisional_schema::ElfSymbolVersionsEntries = typedef std::map<gtirb::UUID, std::tuple<SymbolVersionId, bool> >

Map from gtirb::Symbol UUIDs to a tuple of symbol version identifier and hidden attribute.

ElfSymVerDefs

using gtirb::provisional_schema::ElfSymVerDefs = typedef std::map<SymbolVersionId, std::tuple<std::vector<std::string>, uint16_t> >

Map from version identifiers to version definitions. These correspond to ELFxx_Verdef entries in the ELF section .gnu.version_d. The values in the map are tuples containing the list of versions strings and the verdef flags. The verdef flag may be VER_FLG_BASE (0x1), which indicates that the given version definiton is the file itself, and must not be used for matching a symbol. The first element of the list is the version itself, the subsequent elements are predecessor versions.

ElfSymVerNeeded

using gtirb::provisional_schema::ElfSymVerNeeded = typedef std::map<std::string, std::map<SymbolVersionId, std::string> >

Map from dynamic library names to the symbol versions that they need. For each library, we have a map from version identifiers to version strings.

SymbolVersionId

using gtirb::provisional_schema::SymbolVersionId = typedef uint16_t

Version identifiers are 16 bit unsigned integers.
